I've managed to solve my problem by getting the "lib" files from the ftb unleashed pack and copying them into the folder. This resolves the downloading errors and my problem.

This is using the ftb-unleashed modpack with certain things taken out and added in. All of the mods load but I get a "java.lang.NoClassDefFoundError" with a description of "Exception in server tick loop" Here is the full error message ---- Minecraft Crash Report ---- // Would you like a cupcake?

The problem is, most of the mods I want are only available on 1.5.2 such as buildcraft and forestry. In fact, a lot of popular mods such as industrialcraft are on 1.4.7. I would prefer actual solutions to my problem than someone telling me to just update

I have volunteered to set up a modded server for me and my friends. Forge is obviously necessary because most mods rely on it. I copied everything from the "minecraftforge-universal-1.5.2-7.8.1.738" file to the "minecraft_server.1.5.2" file using winRAR and then clicked on it. The server program did not appear and I got the folders "coremods" and "lib". Here is the server log: http://pastebin.com/YE4BMXKk I am not lying when I say I have looked around for a solution, I haven't found any hope. I know a fair bit about MC stuff as I have made mods and created a modpack of which involved debugging, Please help!
